Abstract: 1277887 Injection moulding STANDARD TELEPHONES & CABLES Ltd 18 Sept 1969 [23 Sept 1968] 45089/68 Heading B5A [Also in Divisions F2 H1 and H4] An array of push-buttons A are interconnected by flexible connecting strips B which are formed integrally with a surrounding frame C. Each connecting strip B is so formed that it acts as a return spring for the push-buttons and also allows only negligible movement of one button when an adjacent button is depressed. Preferably the array is injection moulded from polypropylene with the connecting strips serving as feeds and the button markings incorporated in the button caps during moulding. Alternatively the markings may be carried on plastics caps which fit over the buttons. The array may be used in a telephone set where operation of a button closes a switch contact to generate a signalling code. The frame C may be extended to form a box for housing these components.

Abstract: 1,110,236. Local viewing in colour. COMMISSARIAT A L'ENERGIE ATOMIQUE. 28 Oct., 1965 [10 Nov., 1964], No. 45728/65. Heading H4F. [Also in Division G1] An infra-red or radioactive radiation field is examined point-by-point by a detector which scans the field and the resulting electric signals are applied to control the production of light by a source 5 which exposes a photographic film imaged on a translucent window 16, means (not shown) being provided for effecting relative movement between the film image and window corresponding to and synchronized with the scanning of the field. In accordance with the invention the light from source 5 is given a colour determined by the intensity of the radiation at each point in the field by means of a rotating disc 10 carrying a series of differently coloured filters, the electric signals being arranged to pulse on the source at a time during the disc rotation which is determined by the radiation intensity. To this end, the pulses from the radiation detector are applied to an integrator, the output from which actuates a galvanometer.type mechanism (not shown) to make contact with one of a ring of photo-diodes 7. Each diode corresponds to one of the coloured filters on disc 10, the diodes being illuminated in turn, as the disc rotates, by light from a lamp 26 which illuminates an aperture 23 positioned in the disc so as to scan around the ring of diodes. The diodes control the pulsing circuit of source 5. Thus, dependent upon which diode is selected by the integrator output, the source will be pulsed during the rotation of the disc to illuminate the filter of one particular colour. Provision may also be made to control the pulse rate in accordance with the integrator output so that at each point in the film recording the radiation intensity is indicated by both the colour and number of the recorded spots. The galvanometer-type mechanism which selects photo-diodes 23 may operate with a linear or non-linear law. In a modified arrangement, Fig. 3 (not shown), the galvanometer-type mechanism is replaced by a counter circuit in which the count state is determined by radiation intensity.

Title: Digital/analogue converter with amplitude and pulse-width modu lation
IPC: G08C19/22
Filed: 1973-10-05
Abstract: 1433909 Digital-to-analogue conversion; measuring position digitally INDUCTOSYN CORP 5 Oct 1973 [26 Oct 1972] 46521/73 Heading H3H In a digital-to-analogue converter, pulses representing equal increments (or decrements) of a phase angle are accumulated algebraically to derive signals representing coarse and fine portions of the phase angle, a first pulse train is derived in which alternate pulses have opposite polarity and each pulse has a duration which is a first function of the coarse portion, a second pulse train of the same frequency is derived in which alternate pulses have opposite polarity and in which each pulse has a duration which is a second function of the coarse portion and an amplitude proportional to the fine portion, and the amplitude of corresponding pulses of the first and second trains are algebraically combined. In Fig. 1, the D to A converter is in the feedback path of a servo system in which a digital display 26 tracks the position X of a movable member 41. A transducer 42 comprises a fixed pick-up winding 40 and "sin" and "cos" windings on the movable member 41. The servo system feeds appropriate signals Y to the "sin" and "cos" windings to obtain a null output on line 39. A change in X causes an output to appear on line 39 which is phase detected at 5 to produce a positive or negative error signal at 48. During the existance of an error, clock pulses are counted, up or down according to the sign of the error, by a scale-of-5 counter in 28 to give the fine portion, carries from this counter being accumulated in 30 for the coarse portion. The display 26 receives fine and coarse contributions 63, 64. The coarse portion causes the state of two constantly cycled counters (11, 12), Fig. 3 (not shown) to be offset whereby two appropriately phase-shifted square-wave signals are generated, which are then logically combined to produce two first pulse trains having pulse widths respectively proportional to the cos and sin of the coarse portion of the phase angle for the "cos" and "sin" windings of the transducer 42. Two second pulse trains are produced in 28 having amplitudes of + 2, + 1, 0, -1, or -2 in accordance with the fine portion and having pulse widths equal to the sin and cos of the coarse portion of the phase angle, and are combined in 33 with the cos and sin coarse portion signals respectively In Fig. 9, the solid lines show the resultant waveforms applied to the "cos" and "sin" windings (44, 46) the dotted lines the shape of the first (coarse) pulse trains. The invention allows a greater number of quantizing steps for balancing Y against X for a given clock frequency.

Title: Light measuring and indicating circuit
IPC: G01J1/18
Filed: 1975-11-11
Abstract: 1531275 Light intensity indicator NIPPON KOGAKU KK 11 Nov 1975 [20 Nov 1974] 46575/75 Heading G1A [Also in Division G2]  In a light intensity indicator one of a number of light emitting diodes (LED) 20, 21a, 21b, 21c, 21d is activated in dependence upon the detected light intensity, or, two of the LEDs are alternately activated if the detected light intensity is somewhere between the two intensity levels that the LEDs represent. In one form of the light intensity indicator for a camera the output of a photo-conductive element 5 is fed to two comparators 9 and 10 which also receive the different standard voltages from resistors 2 and 3 connected across a battery. The outputs of the comparators 9 and 10 supply two AND gates 12 and 13 which also receive signals from a pulse generator 11. The gates 12 and 13 drive a reversible shift counter 14 that counts up to a particular value in dependence upon the incident light intensity. The counter's value may be shown by light emitting diodes 20, 21a, 21b, 21c, 21d supplied, as shown via inverter 16 and inhibit gates 17a, 17b, 17c. As the flip-flops making up the shift counter are charged over extra resistors 7a, 7b, 7c and 7d are switched in by F.E.T.s 8a, 8b, 8c, 8d independence upon the direction of counting. These additional resistances alter the input voltage from the photo-conductor in a "step-wise" fashion until the comparator output causes the gates to cease passing pulses. This happens when the incident intensity corresponds to that of one of the levels represented by the lamps 20, 21a, 21b, 21c, 21d. However if the light intensity is "intermediate" two levels, pulses will be driven to cause two adjacent flip-flops to be alternately  turned on and off. The two alternating lamps may appear to remain "on" if the pulse rate is fast enough. In a modification Fig. 3 (not shown) the output of the photo-detector may be modified by associated adjustable circuitry taking into account the aperture size of the camera and the sensitivity of the film. Also the "standard voltage" inputs are stepped up and down by the reversible shift counter instead of the photo-conductor output (as in Fig. 1) until one lamps remains on, or, two adjacent lamps alternate as before. In a further embodiment Fig. 5 (not shown) two photo-conductors are employed, one having a filter in front of it. This results in two light  intensity signals differing by a predetermined amount, that are compared with a fixed standard voltage and processed in a similar fashion to the previous two embodiments.

Abstract: 1,130,170. Catalytic oxidation of hydrocarbons. METALLGESELLSCHAFT A.G. 4 Nov., 1965 [13 May, 1965], No. 46829/65. Heading B1F. In a process for the catalytic oxidation of hydrocarbons in the gaseous phase which is carried out in a tray reactor 1 having a plurality of separate reaction zones a - g each containing a layer of catalyst, the reaction gases are cooled between successive reaction stages by being passed through heat exchangers 4a to 4f. Even with the cooling it is ensured that the inlet temperature of one zone is greater than the inlet temperature of the previous zone. The thickness of each catalyst layer and the concentration of active substances in each layer are selected such that the temperature gradient in a zone decreases from one zone to the next in the direction of flow, shown downwardly. Distributors 5a - 5c uniformly distribute the gas over a catalyst layer. The heat dissipated by the cooling may be used for preheating the reaction gases, or for generating steam or for heating a liquid heat-transfer liquid for use e.g. in a distillation plant. The outlet temperature of the gases from the first reaction stage is at most 550‹C with the inlet temperature of the gas at the last stage at least 50‹C higher than the inlet temperature of the first stage. The hydrocarbons may be admixed to the oxygen containing gas prior to entering the reactor or part of the hydrocarbons may be supplied between successive reaction zones. The temperature pattern may be further controlled by supplying cold air between successive stages. The hydrocarbon may be benzene and the resulting product maleic anhydride, or alternatively the hydrocarbon may be tetrasubstituted benzene hydrocarbon and the product pyro-benzenehexacarboxylic anhydride.
